Checking easements on a house in Keizer? Start with the Keizer plat map, as it records the lot layout that deeds refer to. This Keizer guide covers: where to request a copy, plat versus tax map, and what to look for on the sheet.
The Keizer plat map: start here
For a subdivision near Silverton, look for the plat book reference on the parcel record; that makes the request quick.
Getting to the right map
Property in and around Aumsville can be looked up on the ORMAP statewide tax lot viewer, free to use and open without a login. For a parcel near Gervais, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a home near Salem, the parcel card normally shows the owner of record, assessed acreage, the parcel number and sometimes recent sales.
Marion County in a few facts
Salem holds the county offices, where most land records are kept. Other places on the map include Gervais, Turner, and Silverton, where town lots give way to larger tracts. Roughly 346,741 people live in Marion County (Census estimate, 2023) on roughly 1,181 square miles. Marion County dates to 1843, and some chains of title near Salem are long. Places such as Ankeny National Wildlife Refuge are easy to spot when you zoom out from Gervais.
Keizer and the county around it
Keizer is part of Marion County, Oregon, and the county assessor maps its lots. In and around Aumsville, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Acreage past the town limits near Woodburn generally falls under county rules instead.
Field tips
Most viewers work in a phone browser, handy when you're parked on a road near Gervais, so load it before you lose signal. A saved image of the lot near Aumsville and its lines keeps working without signal.
Replats and vacations
Lots near Turner can be combined or reconfigured by a replat, search the index for replats of the same subdivision; vacated streets or alleys also get recorded.
Plat map vs. parcel map
The ORMAP statewide tax lot viewer draws parcels for taxes, while the recorded plat is the legal document.
What the map can't tell you
The acreage figure is an assessed number; just a licensed surveyor can set the real lines for a parcel near Gervais. Near Turner, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Offices that can help
For assessment questions about property around Woodburn go to the County Assessor, the office behind the parcel record. Questions about what you can build around Woodburn are for the local planning and health departments, town or county, depending on location.
What a plat shows
Easements on the plat near Woodburn limit where you can build or fence; check the plat notes and any covenants.
Ordering the Keizer plat map
For a home near Turner, some counties put plat images online, otherwise call or visit with the reference; small fees are common.
Sections, lots and bearings
Oregon uses the Public Land Survey System, so deeds around Gervais reference sections and townships. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though real sections near Salem vary in size. Keep the legal description for land near Aumsville when you talk to a surveyor.
When there's no plat
Rural land near Woodburn that was never subdivided may have no plat at all; look for a recorded survey for land near Salem.
Next door to Marion County
Marion County borders Clackamas County, Jefferson County, Linn County, Polk County, and Wasco County, and each of those keeps its own parcel map. Ground near Gervais that runs to the line may show up across two assessors' files, so check the adjacent map too. Closer to Salem, the Platbookmapper state page lists every neighboring county map for Oregon.
Deeds, plats and who keeps them
The map is an index, not the title: deeds, subdivision plats and easements covering ground around Turner are kept by the County Clerk. Inherited tracts near Salem may sit on a long string of deeds, so a title company can sort it out on a real sale.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
